New York has confirmed its first death from 'Legionnaires' disease.' Who is at risk? In connection with the outbreak of legionellosis, also known as 'Legionnaires' disease,' New York has reported its first resident death, said the city's health commissioner, Dr. Alistair Martin. The fatality was recorded on the Upper East Side. According to the New York City Department of Health, the outbreak of the disease, symptoms of which resemble severe flu, occurred in the Carnegie Hill and Yorkville neighborhoods of the Upper East Side. Additionally, 71 cases of illness have been reported in the area of the legionellosis outbreak, more than 50 of which resulted in hospitalization. The source of the infection is believed to be the vapor generated in cooling towers located on building rooftops. Those at higher risk include individuals aged 50 and older, as well as those with weakened immune systems due to illness or medication. Doctors also warn about the danger of legionellosis for smokers, diabetics, and individuals with chronic heart, lung, kidney, or liver diseases. While there is no vaccine for Legionnaires' disease, it can be treated with antibiotics. NYC Health emphasizes that the best way to prevent the disease is to monitor the condition of water supply systems, as noted by RTVI US.
